Question

What is the role of mno2 in the decomposition of potassium chlorate?

Answer 1

MnO2 act as the catalyst in the decomposition reaction.

Explanation :

• Decomposition reaction is described as a chemical reaction in which a chemical substance breaks down into two or more chemical compounds when heated. It's thought to be the polar opposite of a combo reaction.
• Potassium chlorate (KClO3) decomposes into potassium chloride and oxygen gas when heated in the presence of a manganese dioxide catalysts.
• We get a balanced equation for the reaction is - 2KClO3−→△2KCl+3O2
• When MnO2 (Manganese dioxide) is present, the decomposition of potassium chlorate is accelerated. It enables for lower-temperature breakdown.

Answer 2

Answer:

Manganese dioxide ($MnO_{2}$) functions as a positive catalyst. With the help of the $MnO_{2}$ potassium chlorate will decompose, resulting in the production of potassium chloride and oxygen.

Explanation:

A decomposition reaction is a chemical process in which a chemical substance breaks down into two or more chemical compounds when heated.

Potassium chlorate is available in crystalline form. The reaction proceeds in the way that oxygen is released when the substance, potassium chlorate, is heated, leaving a potassium chloride residue.

In the presence of $MnO_{2}$, which is a very good catalyst for the decomposition of potassium chlorate, the decomposition is accelerated. It enables decomposition to take place at a lower temperature.

The balanced chemical equation is as follows:

$2KClO_{3}$ + Δ → $2KCl$ + $3O_{2}$
